The latest breakthrough for your phone protection is tempered glass screen protectors. Your smartphone is a costly investment but it can literally shatter into pieces when it hits the floor or a rock if it drops. Obviously, you would want to protect your smartphone against any damage and keep it in best condition possible that is why it is important to think about purchasing the best tempered glass screen protector.

Tempered glass screen protector are thin layers of hardened glass that can be installed on top of your phone screen. It absorbs all scratches and shocks that would otherwise be impacted on your phone’s screen without transferring them to your phone’s screen. Moreover, it is resistant to most scratches that your regular phone screen cannot sustain. But the main question is…

What are tempered glass screen protectors made out of?

This glass is made by heating normal glass and then quickly cooling it in a process known as tempering. This results into a glass whose characteristics are different from normal glass. It breaks differently. In case of any breakage, it creates rounded edges of glass pieces compared to jagged wrecks of regular glass. Compared to regular glass, tempered glass is more heat resistant.

Tempered glass protector features multiple layers. At the bottom, it is an absorbent silicon which is then followed by a PET (polyethylene terephthalate) film, an optically clear adhesive tempered glass and finally an oleophobic coating. Tempered glass is five times thicker than the regular glass. Oleophobic coating is some sort of surface treatment that improves screen usability as well as protecting the surface against water and scratches.
Tempered glass is subjected to thermal treatment or hydrofluoric acid treatment. These treatments improve its compressive and tensile stresses at the surface thus making it tougher. This glass is more resistant to surface pressure or heat.

The best tempered glass screen protectors have the following properties:

• Excellent responsive touch
• Perfect adhesion
• Complete transparency
